Jonny Brownlee is back from injury and looking forward to competing in the ITU World Triathlon Grand Final in Chicago.
Jonny suffered a stress fracture in his left femur earlier this summer, and expects the run to be hardest part of returning to competition.
Olympic Champion Alistair Brownlee's season is already over following ankle surgery two weeks ago, leaving the field clear for Spain's Javier Gomez as he aims to become the most successful triathlete in ITU history.
